Had the same message. Got a loaner from Garmin and had the unit repaired.
It happened about 30 days after install.

I'm having trouble with the com in my Garmin 430. The audio reception was
getting scratchier and scratchier on it, then in the MSG screen, I get an
error like: "com requires service".

My local avionics guy says all he can do with it is ship it back to
Garmin.

Anyone else had this problem?
